Recently my 1966 Mustang was dipped to remove everything (rust, paint, seam sealers, etc) and was painted last month. Now the car is back home and as I look in some spots like the hole leading to the cowl and other spots have red oxide primer which has pealed and wanted to fix the troubled areas. What would you suggest for fixing hard to reach spots like holes leading to the cowl, tiny rear shock holes, akward interior quarter panel areas? I would like to prime them and get a couple of cans of color match to fix the areas.
